| 摘要 |
The subject of the invention is an antenna which is common to the ILS and MLS type radio navigation systems. The antenna is made up of a track localiser ILS antenna whose central part 1 is replaced with a conventional MLS antenna ahead of which are arranged radiating elements 7 which, in combination with the lateral parts 2, 3, deliver ILS signals; the MLS antenna 1 provides a reflector function for these radiating elements 7. These radiating elements 7 are chosen so as not to disturb substantially the MLS radiation. <IMAGE> |
